LIGHT-REFLECTING DEVICE.

Specification of Letters Patent.

Patented Jan. 20, 1914.

To all whom it may concern:

Be it known that LEARL G. MCKINNIE, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Light-Reflecting Devices, of which the following is a specification.

This invention relates to improvements in light reflecting fixtures or chandeliers especialllsy adapted for use with an electric light bul Theimprovements embodied herein pro vide a new and usefulconstruction of reflecting chandelier or fixture adapted to re fiect the rays of light against the ceiling or other body from which the fixture is suspended; to diffuse a portion of the light flux downwardly and outwardly for the purpose of illuminating a bowl, globe, or other device adapted to conceal the main reflector and the source of light, and also to produce an ornamental effect desirable in fixtures of this class.

A further object of the improvements embodied herein is to produce a fixture of simple and economical construction which may be readily disassembled and cleaned.

A further object of my invention is to provide means whereby the light unit or bulb will be held at a certain distance from the reflector so that the maximum illuminating efliciency will be maintained.

Other objects of general utility and novelty not enumerated are conserved by this invention as will be apparent to those skilled in the art to which it relates.

In the accompanying drawing, forming a part of this application, I have illustrated a preferred embodiment of my invention in detail, but wish to be understood that such details may be varied without departing from the scope of my invention.

In said drawing :-Figure 1 is a view partly in section and partly in elevation of a chandelier fixture embodying my invention; Fig. 2 is an enlarged fragmentary detail showing one of the bracket arms employed in my invention, and Fig. 3 is an en larged sectional view showing the member which cooperates with the members shown in Fig. 2.

Referring to the details of the drawing, 4 represents a translucent bowl of glass, porcelain, or other suitable material, which may be of any desired shape and ornamental finish. The bowl 4 is formed with an outwardly flaring edge to which is preferably fitted a metal band 4. Suspended within the bowl 4, and supported from the free edges thereof, is a bowl shaped reflector 5, the inner surface of which is of highly refleeting properties and the outer surface of which is treated tomake the bowl opaque. Suspended in an opening 6 in the bottom of the reflector 5 is a small bowl shaped member 6, which is preferably made of opal lass or other material having similar difl'using properties. This diffusing member 6 is suspended from the reflector 5 by its out wardly flaring edges which overhang the edges of the opening 6 in the reflector.

The relative diameters and curvatures of the globe 4, reflector 5, and diifuser 6, are such as to effect the desired illumination and decorative results, and may be varied to suit any special requirements. The three mem bers described, assembled as indicated, are supported by cars 7 having threaded holes in their lower ends engaged by screws 11, which also engage correspondingly threaded openings in the rings or bands 4;. Projecting inwardly and upwardl from each of the ears 7 is an arm 8, in which there is an elongated slot 8, the lower end of the arm being riveted to the ear 7 by a rivet 8". Near the upper end of the ear 7 is secured a hook 10 by a rivet or screw 10. The arm 8 is detachably connected with a bracket 9 by means of a slot 5) near the lower end 9 of said bracket, and by means of a clamp 9", connected with the bracket 9 by a pivot 9" and having near its outer end a slot 9' which corresponds to and re isters with the slot 9. Secured to the under side of the clamp 9 is a flat spring 9 the tension of which is normally exerted to throw the clamp upwardly and away from the bracket end 9, as shown in Fig. 2. The slotted ends of the bracket 9 and clamp 9 are inserted in the slot 8 and the expanding clamp 9 secures the bracket 9 against accidental displacement or disconnection from the ear 7.

Three or four of the ears 7 and :1 corresponding number of brackets 9 will be used and the upper ends of the several brackets 9 will be rigidly secured to rings 13, 14, which embrace the socket of the electric lamp 15, thus centering the 1am with reference to the reflector 5, and also indicating the proper relatire distance in avertical plane between said lamp and said reflector. The suspending chains 12 are connected with the hooks 10.

The form of connection between the brackets 9 and ears 7 facilitates the detach-- mentof the bowl with its reflector at one side of the supporting-brackets 9 for the purpose of cleaning said reflector without causing the accidental-disconnection of the other brackets 9 and ears/7.

' The interfitting arrangement bet-ween the bowl 4, the reflector '5, and difl'user 6, prevents dust from entering the bowl 4. I

Having thus described my invention, what I claim as new, is:-

1. An illuminating device comprising a bowl-0f light difl'usin material, an opaque reflector arranged wit in said bowl for directing light rays upwardly and outwardly, and having an opening therein, a light diffusing member arranged in said opening and adapted to difluse the light rays fromwithin said reflector against the inner walls of said bowl, in combination with a lighting unit, means connected with said bowl for supporting said unit within said reflector, and means for suspending said bowl.

2. An illuminating device comprising a bowl of translucent material, a reflector arranged within and supported by said bowl and having a central opening in its bottom, a translucent bowl shaped member arranged in said opening and adapted to difluse the light rays downwardly and outwardly against said first namedbowl, a lighting nose-non unit suspended in said reflector, and means for holding said lighting unit in fixed relation to said reflector.

3. An illuminating device comprising an outer bowl of translucent material, an opaque reflector arranged within said bowl, a light difl'user arranged within said reflector and adapted to direct light rays downwardly and outwardly a ainst said outer bowl, said reflector and difl'using device adapted to form a closure for said outer bowl, means for suspendin said outer bowl,

l said means including detac able connections with said bowl, and means for supporting a lighting unit-in fixed relation to said re-. "Hector.

4. An illuminating device comprisin three bowl-shaped concentrically arranged members, the outer of said members being of light diffusing material, the inner member bein of light-reflecting material and the interme iate member being of light transmitting materialand so arran edas to transmit light rays from within t e inner memher to the entire area of the walls of the outer member, in combination with a light producing member arranged in the inner member.

' lln testimony whereof I aflix my signature in the presence of two witnesses.

EARL C. MGKINNIKE.
